GREENFIELD — Lattice multiplication? Partial sums addition?
It’s all Greek to parents who learned to solve math problems by traditional means.
But these seemingly foreign concepts are laying the mathematics foundation for hundreds of Greenfield-Central students.
Called Everyday Mathematics, the likes of lattice multiplication and partial sums addition are part of a pre-kindergarten through sixth-grade curriculum developed by the University of Chicago School Mathematics Project and adopted by the Greenfield-Central school corporation in 2010.
